In the US state of Virginia, some state highways have been specifically designated to serve state parks and state institutions. State Route 217 and the range of numbers from State Route 302 to State Route 399 are currently used (non-exclusively) for this purpose. For a list of very short Virginia primary state highways, see List of primary state highways in Virginia shorter than one mile.
